> Running a modified version of the Database Opensource Test Suite (DOTS)
> (v1.1.1) test case ATCJ2 (auction "simulation"), available from
> http://sourceforge.net/project/showfiles.php?group_id=3382, resulted in an
> "OutOfMemoryError: Java heap space" after 57 days, 13 hours and 21 minutes.
> The test run has previously been described on derby-dev:
> http://www.nabble.com/Long-running-testing-of-10.2.1.5-t2382591.html.
> The modifications to the original test case were mainly to avoid the type of
> errors described in
> http://www.nabble.com/OutOfMemoryErrors-when-testing-Derby-with-DOTS-t1010027.html.
> Indeed, this is a different, yet similar error.
> Heap size (both client and server JVMs) was:
> -Xms128m
> -Xmx128m
> The test was run against the 10.2.1.5 release candidate, but since this
> version does not exist in Jira, and the delta between 10.2.1.5 and the
> released 10.2.1.6 is minimal, 10.2.1.6 is marked as the "affects version".
